Having trouble getting a max( ) value

Hi,

So I want to start off a pipeline by getting a maximum value to use later on
in the process via the following max(//page/id) which works in oxygen as an
xpath on the input file returning a value around 15000. I've verified the
correct input file is loading. In the following code however the value
returned is a zero length string. So what am I doing wrong?

 <p:group name="extractMaxID">

    <p:load>
      <p:with-option name="href"
select="$hrefFullWikiDumpInputToGetMaxIDValue"/>
    </p:load>

  </p:group>

  <p:variable name="MaxID" select="max(//page/id)"/>  // is returning a zero
length string


Secondly when I put the variable within the p:group I get the following
error using Oxygen XML Editor 12.1, build 2011011116

E [Calabash XProc] Unexpected step name: p:variableUnexpected step name:
p:variable.

<p:group name="extractMaxID">

    <p:load>
      <p:with-option name="href"
select="$hrefFullWikiDumpInputToGetMaxIDValue"/>
    </p:load>
   <p:variable name="MaxID" select="max(//page/id)"/>

</p:group>

Is that normal? (hmm..I almost recall this may have already been talked
about on the list, sorry if that's the case)
